Titanium Exhaust Pipe

Titanium alloy density is about 60% of the steel,on the premise of the same size, it will be lighter.Because of such features, it has been applied in many high-tech fields, such as the aviation industry.Its high strength, heat resistance, of course, is also factors that cannot be ignored.With the rising demand for cars, especially sports cars, people request it as far as possible to light, titanium alloy material is undoubtedly very accord with the demand, but it cannot be spread on the original basic car because the material is expensive, then personality modification can show its advantages in the "optional".On the market, different purity of titanium alloy price are different, the higher the purity,the better of the degree of stretch(bend), the higher temperature resistant degree.

High purity cannot explain the titanium alloy can be unlimited bent, so some curvature is bigger place, the titanium alloy material will also to cut, forming and welding.On the other hand, the curvature is not big, can use the machine to bend.Titanium alloy welding is harder than steel, only the best welder can be selected for titanium alloy pipe welding, the requirement of welding is high.In addition to the price of material, the processing is difficult can also explain why the titanium alloy pipe is relatively high.The characteristics of lightweight of titanium alloy, make its become the object of the sports car chase.Through special processing, tail tip can show various colors.

Titanium alloy with high strength, good corrosion resistance, high heat resistance, etc. Titanium alloy in seawater in the humid atmosphere and work, its corrosion resistance is far better than stainless steel;To pitting corrosion, acid corrosion, stress corrosion resistance particularly strong;The alkali, organic chloride, chlorine, nitric acid, sulfuric acid has excellent corrosion resistance, etc.Therefore, the use of exhaust pipe can increase the service life of titanium alloy.

Titanium alloy is a new kind of structural and functional material, it has excellent comprehensive performance, density is small, higher than strength. The specific strength of titanium alloy is higher than the aluminum alloy and steel, ductile and steel also. Titanium alloy corrosion performance is good, the working temperature of heat resistant titanium alloy can reach 800 degrees. Titanium alloy is also very light, use on the car's exhaust in order to reduce vehicle weight so as to achieve the purpose of speed faster. Another advantage is the ultra-thin titanium alloy pipe play a clear and crisp exhaust noise, purplish blue sheen changes when driving is also full of attractiveness. The beautiful purple blue light titanium alloy tail tip, to add to the rear of the car Racing.

Titanium Tube Heat Exchanger

1 the application of titanium in chemical industry

titanium and titanium alloy, not only the large strength, good toughness and weldability, more important is that it has excellent corrosion resistance.In oxidizing, neutral and chloride ions in the medium of its corrosion resistance in some places more than ten times or even dozens of times of SUS304 stainless steel. Thus since the 1980 s in China, is widely used in alkali, salt, urea, pesticide, synthetic fiber, organic synthesis, pharmaceutical, hydrometallurgy, such as chemical process industry.

2 application of titanium tube heat exchanger in the oil refining chemical. 

titanium  has excellent corrosion resistance, high specific strength and good processing performance, thus is earlier used in the oil refining chemical industry, in the United States, Europe, Japan, titanium has been used more than 40 years, has nearly 20 years in China.

Titanium CN is mainly used in cooler, heat exchanger, condenser, and in not only apply to the water cooler, can also be applied to oil and gas heat exchanger;Not only can be used in the new system of titanium heat exchanger, also can be used as a technical modification for titanium pipe to replace copper tube coolers (still with a brass plate).

Japan since 1955 in titanium solve atmospheric and vacuum low-temperature H2S corrosion - HCl - H2O environment problems.Europe and the United States as early as in 1960 will also titanium heat exchanger used in refineries, initially mainly to solve the corrosion of seawater, brackish water and polluted water, and then used to prevent the lower quality of crude oil and corrosive gas corrosion of equipment.Due to domestic in recent years, many imported crude oil from the Middle East, and high sulfur content of crude oil, this brings the refining equipment to improve the technical transformation of material, to adapt to the refining high sulphur crude oil in the Middle East the anti-corrosion requirements.Domestic crude oil with the increase of production, the sulfur acid salt is increasing, the diversity of oil source and inferior, make the equipment corrosion problems more outstanding, improve the material standards, selection of titanium manufacture certain key sectors severe corrosion of heat exchange or condensing cooling equipment, oil refining chemical plant is one of main measures of energy saving and efficiency.

The advantages of titanium dentures

Good biocompatibility

Titanium in contact with the human body without sensitization, growing phenomenon, cause cancer, birth defects can be combined with bone tissue, epithelial, connective tissue well, sso it is the metal material which has the best  biocompatibility.

The physical properties of titanium

1. The density is small, the density of titanium is 4.51 g/cm3, about a quarter of gold (19.38 / cm3), cobalt chromium alloy (8.5 g/cm3) 1/2. So the titanium denture can reduce the burden of oral hard and soft tissue, is helpful to oral health.

2. Low heat conduction rate: Thermal conductivity of titanium (16.3 ~ 18 w/m. ℃) is only 1/17 of gold, and titanium titanium inlay, coronal protection pulp tissues from the advantages of hot and cold stimulation.

3. The little shrinkage: titanium line shrinkage rate of 1.75%, lower than co-cr alloy (2.13 ~ 2.24%), stainless steel (1.95 + / - 0.15%) and gold (1.76%), therefore the suitability of the titanium denture is wonderful.

4. The X-ray shoot half resistance: X-ray photos can show titanium crown tooth tissue lesions.

5. Nonmagnetic: titanium denture will not be magnetized in strong magnetic field.

The chemistry of the titanium 

On the surface of titanium passivation film with acid corrosion resistance, so the titanium denture is not easy to corrode.

The mechanical properties of titanium

1. The hardness of titanium (HK240) between the enamel (HK345) and dentin (HK40 ~ 60), so the titanium artificial crown of occlusal surface will not too much wear on the jaw tooth occlusal surface.

2. The specific strength (tensile strength/density) of titanium is high,which is 1.3 times of aluminum, 1.5 times of steel. in 253 ~ 600 ℃ temperature range, the specific strength of titanium is the highest in metal material.So titanium denture solid, durable.

The difficulties in titanium production restoration,

1. high melting point

Titanium melting point 1668 ℃ + 4 ℃, which is  243 ℃ ~ 378 ℃ higher than co-cr alloy(1290 ℃ ~ 1425 ℃), thus, regular dental titanium casting machine not melt the metal.

2. Titanium extremely easy oxidation at high temperature

Chemical properties of titanium CN lively, easy to form the oxide film at high temperature, even at room temperature, titanium new aspects as long as the air exposure 1 ms, 10 a black is formed namely titanium surface thickness of oxide film,and increased to 50 ~ 100 a 1 min later.

3. Titanium casting performance is poor
Titanium density small, titanium liquid flow inertia small, illiquid, and high cooling speed, lead to the castability value is low.So you need to have enough pressure casting to make complete casting foundry.

The Benefits of Titanium Frame

Titanium is a essential materials in aerospace science, ocean science and nuclear power and other advanced science, industrial;Titanium metal rack 48% lighter than normal, and strong toughness, acid and alkali, corrosion resistance, high stability, high strength, good elasticity, etc, accord with human body engineering, titanium non-toxic to human body. Without any radiation.

Titanium is divided into a titanium and βst titanium. Refers to the different heat treatment process.

glasses frame titanium CN is high hardness, Good flexibility, Long-term use of deformation, light weight, do not fade. These are the benefits of titanium frames. Always attaches great importance to the health of Japan, recently found that titanium has the effect of stable current to the human body, relieving muscle taut skin, spirit is easy to get loose, muscle also gradually relaxed.

In the human body has a small electrical current flowing in from the brain to the whole body, from body to brain information is all depend on the flow of the current has long been under inner pressure and electrical products, such as computers, electromagnetic waves emitted by an outside under the impact of the factors, the body electric current, in fact, there have been more chaos, the result often lead to fatigue, muscle stiffness, pain and other symptoms, or problems.

Pure titanium with special current features, can lead ion electronic fluctuations, made the current tendency of ionization;And positive and negative ions can quickly adjust the body biological current disturbances caused by electromagnetic waves caused by the bad influence, have beneficial physiological effects on human body.

People inherit the spirit of the pressure and the external environment, especially there are a lot of ionizing radiation in the environment of electromagnetic wave, such as: mobile television microwave ovens and other electrical appliances, computer, for a release of electromagnetic wave is caused by the body often state of chaos, current affected so can cause autonomic nerve disorder, pain, muscle stiffness occurred in May by it to the movie, and thus a threat to the health.Using liquefied titanium products, can immediately have chaos body current effect, pain for ease, the body for maintenance.

Titanium frames more expensive than other metal frames, one of the reasons is the titanium refining cost is too high. Titanium refining today like aluminium refining before the 19th century, cost is high, the output is limited, therefore only used in some important fields, such as aerospace, electronics, precision instrument manufacturing, etc.

The second is the complex production process of titanium frame. Titanium metal frame production of titanium metal frame production need special processing equipment, special welding technology and electroplating process, machining process, the production cost is high.
